BACK ORDER REALLY?I should have gone to TELKOM mob

So disappointed with Vodacom. I have been a customer for many years. Yesterday I called their contact centre to cancel my contract, but instead was persuaded to take out another deal. Upon conclusion of the new contract was informed that delivery would take between 3-5 working days. My current phone that was using then unfortunately had to go in for repairs, so doing the correct thing I contact the contact centre, after being chased in circles for about 45 minutes just to change the contact number in case of delivery, I eventually go to the online chat portal, where then after explaining myself AGAIN, I get told that my order has been placed on back order? really? Why did the consultant not tell me that they did not have stock? now I have to wait an extra couple of days for my new device. I also gave my work address as a delivery address and I called to inform them that I will be on leave on Friday in case delivery needs to happen then, and get told that they don't need the information because delivery will probably be delayed even more. I will be away for the next week or two and now have to wait extra days because Vodacom does not deliver on their promised service.
